There is an interstate near where I live. It has ton of high trees on both sides. There are a lot of signs (about 25) with serious blockage by those trees. Those signs are blocked so badly, that it's hard to see tel number even if you wanted to advertise.

If signs were owned by one company you could say this was crazy move by a one guy. But they are owned by maybe 5-6 different companies. So, I am curious, how could this have happened? Did those 5 companies build 20y ago and all forgot to calculate tree growth completely? That's $1.2MM lost!
